Depiction in the series

Double Diamond first appears in The Cutie Map - Part 1 welcoming Twilight Sparkle and her friends when they arrive at Our Town. He and Party Favor introduce them to the village's founder Starlight Glimmer. He appears to be among Starlight's more faithful followers, as he shows disapproval toward Sugar Belle for talking so openly to the Mane Six. Later in the episode, he accompanies Starlight in leading the Mane Six to the cutie mark vault and takes part in the trap that Starlight springs on them.

In The Cutie Map - Part 2, Double Diamond personally brings the Mane Six's cutie marks to Starlight Glimmer's cottage, curious as to what she intends to do with them. Later, when Starlight is revealed to still have her cutie mark, the betrayed Double Diamond leads the other villagers in a revolt against her. He uses the "Staff of Sameness" to shatter the vault's glass covering and release the cutie marks unto their owners.

Double Diamond joins Party Favor, Sugar Belle, and Night Glider in pursuing Starlight, during which he recovers his old skis and causes an avalanche on top of Starlight. After Starlight escapes, Double Diamond expresses excitement in getting to know his fellow villagers all over again.
